The GICv4 architecture doesn't make it easy for save/restore to work, as it doesn't give any guarantee that the pending state is written into the pending table. So let's not take any chance, and let's return an error if we encounter any LPI that has the HW bit set. In order for userspace to distinguish this error from other failure modes, use -EACCES as an error code.
